| 20090042440 | Coaxial plug-in connector comprising a contact mechanism for electrical contact - A coaxial connector for insertion of a complementary coaxial connector, in which a switching mechanism having an electrical contact is arranged and formed in the coaxial connector that the electrical contact is closed when there is not a complementary coaxial connector inserted in the coaxial connector, and the electrical contact is open when there is a complementary coaxial connector inserted in the coaxial connector, the arrangement made so that the switching mechanism has a cylindrical first conductor part which may be expanded and/or compressed radially with elastic resilience, and which makes electrical contact with a second conductor part of the switching mechanism, the first conductor part arranged and formed that a complementary coaxial connector which is inserted in the coaxial connector expands the first conductor part radially or compresses it radially, thus breaking the electrical contact between the first conductor part and the second conductor part. | 02-12-2009 |

| 20110094919 | ARRANGEMENT OF A PLURALITY OF MOISTENED COSMETIC PADS AND METHOD FOR THE PRODUCTION THEREOF - An arrangement having a plurality of moistened cosmetic pads based on nonwovens which are piled into a closable packaging container in order to distribute to the final consumer and to prevent evaporation. The pads have, on average, a moisture content of at least 200% of the dry weight thereof in the arrangement, the pads have a fiber structure made of staple fibers, are individually moistened and have a homogeneous moisture content such that the difference of the average moisture content of the pads which are arranged in the upper and in the lower quarter of the stack is, at a maximum, 30% of the average moisture content of all of the pads. | 04-28-2011 |

| 20090134676 | Vehicle seat with a seat heater - A motor vehicle seat with a seat heater comprises at least one heating element with metallic heating and/or contact conductors which are uninsulated or insulated with thin paint layers and which are applied to a carrier material. A textile layer with a liquid-repellent impregnation formed by an impregnating agent is arranged between the surface of the seat in contact with the user and the heating and/or contact conductors. | 05-28-2009 |

| 20090039283 | IONIZATION OF DESORBED MOLECULES - An ion source generates ions from analyte molecules which are desorbed from a sample on the surface of a sample support in a pressure range of approximately 30 to 300 pascal. Reactant ions are generated in a separate ion source and guided by ion guides to the point in front of the sample or to a reaction chamber in which the desorbed molecules are located. The reactant ions ionize the desorbed molecules to form analyte ions. The analyte molecules can be mixed in matrix material or adsorbed on the sample support surface without additives. The desorption can be continuous or pulsed, for example by light from lasers or diodes. | 02-12-2009 |
| 20090305327 | Mass Spectrometric Determination Of Blood Enzyme Activity - The invention relates to the determination of the nature and strength of enzymatic activity in blood using mass spectrometric measurement of a profile of the reaction products. The determination of the enzymatic activity can be used for medical diagnostics, for example, and also to check the effectiveness of medication. The invention provides a method whereby adding probe substances usually not present in blood offers standardized substrates for measuring the enzymatic activity. The probe substances may be added to whole blood, plasma, or serum. The mass spectrometric measurement of the reaction products, after their reversible immobilization on actively binding surfaces of solids, for example, can deliver biomarker patterns of the reaction products which may be indicators for metabolic anomalies or diseases, since these are often accompanied by the formation or activation of characteristic enzymes. | 12-10-2009 |

| 20090084949 | EVALUATION OF SPECTRA IN OSCILLATION MASS SPECTROMETERS - The invention relates to mass spectrometers in which ion clouds are stored in two spatial directions by radial forces while oscillating largely harmonically at a mass-specific frequency in a third spatial direction perpendicular to the other two, in a potential minimum, the shape of which is as close to a parabola as possible. Analysis of the oscillation frequencies of these ion clouds, preferably by a Fourier analysis, leads via a frequency spectrum to a mass spectrum. The frequency spectrum is analyzed to identify false signals in the frequency spectrum as harmonics and eliminating them where necessary. | 04-02-2009 |
| 20090294647 | MEASURING THE MOBILITY OF MASS SELECTED IONS - In an ion mobility spectrometer (IMS) coupled to a mass spectrometer (MS), the ion current from a suitable ion source is modulated with an analog modulation having a smooth modulation function, whose instantaneous frequency varies with time over a wide frequency range. The modulated ion current is continuously fed through a mobility drift region into the mass spectrometer, where the temporally varying ion current profile of at least one ion species is measured. The mobility spectrum of the ion species is then generated by correlating its ion current time profile with the modulation function. | 12-03-2009 |
| 20090294651 | EVALUATION OF FREQUENCY MASS SPECTRA - The invention relates to the evaluation of mass spectra from mass spectrometers in which ions are excited to mass-specific oscillating or orbiting motions, and the ion motion is recorded as a time signal. The invention provides methods to detect parameter drift that occurs during the recording of a time signal in such a “frequency mass spectrometer” by analyzing the instantaneous frequency or the phase spectrum of a frequency component, and provides a method to correct for influence of the frequency drift on the mass spectrum correspondingly. In one embodiment a Fourier transformation converts a measured time signal into a frequency spectrum and examines the phase spectrum of a frequency component to establish whether this phase spectrum deviates from the phase spectrum of a harmonic time signal. The phase spectrum of a harmonic time signal is either linear or constant. In another embodiment the time domain signal is processed using a Short Time Fourier Transformation function to determine an instantaneous frequency, which can be used to correct the parameter drift, yielding a corrected time signal. From the corrected time signal a mass spectrum with better mass resolution can be derived, as can be seen from corrected mass signal profile compared with uncorrected mass signal profile. | 12-03-2009 |
